Radiation Solutions RS-125 Super-SPEC
Hand Held Gamma-Ray Spectrometer

The RS-125 SUPER SPEC is the industry standard in portable handheld gamma ray survey devices for geophysical applications.

It offers an integrated design with a large detector for survey or search, direct Assay readout, a scan mode and data storage.

It offers weather protection with ease of use. As well Bluetooth (BT) connectivity provides wireless connection to a Bluetooth enabled external GPS receiver, earphone or computer.


Survey Mode—The total count readout is typically set at 1x / sec rate, the range is variable from 1 - 20 sec. integration. When used with a GPS receiver, data can be stored and profiles produced. Ideal for both area and drill core scanning.

Assay Mode—Provides the concentrations of K, U and Th. The user can select the desired sample time from 30 to 1800 seconds.

RS-Analyst Software—The RS-125 comes complete with utility software to download the data that is stored in the memory. All data in memory is output via Bluetooth or USB to the RS-Analyst program on a PC.
